Edifier vs onkyo ?

Hello all !

I’m a beginner in turntable and audio setup. I now have a AT-LP70xbt-BZ as turntable and Edifier R1280T as speaker. I was offered an onkyo tx-8050 amp and two big speakers (like 40 inch high). Is it worth it to make that change ? Will I hear a difference and is using that amp better than the one in the turntable ?

Thanks a lot !
